Today, computers are no longer boring beige boxes that you often find in stores, like those we've seen about 10 to 15 years ago. Instead, the average PC is adorned with fancy lights and blinking LEDs that makes it look very much like one of those large machines you find in old 70s TV series like Six Million Dollar Man. Of course, machines like that have no purpose and it does nothing more than just make irritating beeps and flash its lightbulbs in an orderly but chaotic manner. The fancy designs that we find today are not totally useless, like what many of us tend to believe, but are actually part and parcel of the PC's overall health and functionality.

Towards the end of the last decade, we saw Cooler Master introducing a totally new concept for PC casings and enclosures. Instead of the traditional stamped steel sheets that's normally the main raw material for most casings, Cooler Master designed and built their first ever aluminium-based casing. Known to most of us as the ATCS (Active Thermal Convection System), the all aluminium case caught every hardcore DIYer's attention with its sleek, lightweight and unique design. Basically, it was at this point of time that users began to feel a greater need towards casings that does not only look good, but function well with high-performance setups as well.

Years have passed and Cooler Master is still at it with their brand of cool casings and accessories. We believe that many would agree that their designs are still one of the best in the industry. However, as with all good products, there is always a premium price tagged to them. But when you want something to look good, there's no reason why you should not spend your well-earned money to get them. After all, they are often not only about looks and design, but are actually useful for the overall system as well.

In this article, we look at two of Cooler Master's add-on peripherals known as the Musketeer and CoolDrive 4. These add-on units are installed into the casing's 5.25-inch drive bay and some power users deem tham as essential companions to their system.
